Can you also bump the commit referenced by bazel here:

mlir-tutorial/bazel/import_llvm.bzl

Line 12 in 6b2f19e

LLVM_COMMIT = "29b92d07746fac26cd64c914bc9c5c3833974f6d"

?

[mtsokol]

Ah right, I missed bazel build. Done!

[mtsokol]

Ok, now it should be ready, can you retrigger CI?

[j2kun]

I'm guessing you may need to substitute some of the references to mlir-cpu-runner in

rg mlir-cpu-runner tests
tests/BUILD
16:        "@llvm-project//mlir:mlir-cpu-runner",

tests/lit.cmake.cfg.py
49:    "mlir-cpu-runner",

tests/CMakeLists.txt
11:    mlir-cpu-runner

tests/ctlz_runner.mlir
8:// RUN: | mlir-cpu-runner -e test_7i32_to_29 -entry-point-result=i32 > %t
26:// RUN: | mlir-cpu-runner -e test_7i64_to_61 -entry-point-result=i64 > %t

Probably sed -i 's/mlir-cpu-runner/mlir-runner/g' tests/**/* would suffice.

All green now!
